The Provision of Defenses against Internet-based Attacks

INTRODUCTION Internet-based attacks have become an important concern to the government and business since more systems are reliant upon the Internet to exchange information. Without a secure Internet infrastructure, neither E-commerce such as online purchasing nor E-democracy services such as online voting can be conducted successfully. For business, both Internet worms and distributed denial of service attacks were listed among top ten security concerns of more than 1,230 organizations globally (Ernst &Young 2004). For government, preventing Internet-based attacks has been an important issue in national plans to secure critical infrastructure (WH 2003).
